IMPROVEMENT IN PLOUGHS.

TO ALL WHOM IT MAY 'CONGERNz' Beit Aknown that I, GEORGE GIB-ns, of Canton, in the county of Stark, in the State ot' Ohio, have invented s. new and improved Mode of Preventing Ploughs from Choking by the accumulation of stubble, weeds, or other rubbish; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

lIy invention consists in providing a vplough with a parallel rod of wood or iron, retained by a slotted support to the side of the beam, and terminating at that end in a rectangular flexible fork or hook, the whole,

actuated by a vertical lever, pivoted at its middle on the handle, within easy grasp of the ploughman, and attached to said rod.

By reference to the drawings, the device codsists of a lever of wood, a, about twenty inches long, pivoted at its middle on the beam handle, at a. point within reach of the ploughmau; a rod of iron or wood, b, of required length, jointed at the lower end of said lever a, and resting in a slotted support, d, which is fastened to its place on the side` of the beam. t the forward end of said rod ZJ, hanging at an angle, is a hook or tine, e, and made lexible by the `joint c, so constructed that it will be rigid when in position shown, and fiexible for return stroke.

Figure l represents thema-chine in position ready for operation.-

As soon as stubble'or other rubbish shall gather in sufficient quantity, a pull on the lever a will thrust the rod bland h oole forward, pushing said rubbish oi, and thus cleaning the plough. If, by negligence, the rod and hooi:` should be kept in this position, and thus allow the stubble to get behind said hook, in returning, by a push of thelever a, said hook will yield at the joint, and slide over the rubbish, and thereby get into its first and proper position ready for another thrust. Should a stone or other uuyielding substance come in Contact with the point .ofthe hook, the slot will allow its rising up and over the stone, and prevent breaking. The slot d, with a rigid rod and hook, will enable said rod and hook to answerl the purpose of the joint c by allowing them an upward and backward movement over'tbe rubbish, which I contemplate using. i

What I claim as my invention, and desire to secure by Letters Patent, is-v The lever a, rod b, joint c, and slot (l, constructed, arranged, and operating in the manner and for the pur-l pose set forth.
